Eliminate biological fouling and increase throughput. In just four easy cycle steps, the Recoflo® Water

Softener outperforms other softeners with superior efficiency, reduced costs, half the brine, and twice

the throughput.

What is the Recoflo® Water Softener

Eco-Tec’s Recoflo® Water Softener utilizes the next

generation of ion exchange with compressed bed,

counter-current technology. With the consistent

philosophy of a simple package with proven reliability,

the Recoflo® Water Softener produces softened water

at lower operating and total installed costs.

The Recoflo® Water Softener can produce water with

less than 0.1 mg/L total hardness using half of

the brine required by other softeners. This high

performance is the result of the rapid, proprietary,

exchange kinetics of Recoflo®, that allows for the

efficient use of brine and water while eliminating

biological fouling.

How Does the Recoflo® Water Softener Work?

The Recoflo® Water Softener has proven, consistent

performance with each of its key features offering up

to 2 times higher throughput rates than other

softeners:

Short bed height and small resin volumeRecoflo® resin beds are only 6 inches (15 cm) to 24

inches (60 cm) in depth, requiring only up to 15% of

the resin volume required of conventional ion

exchange systems.

Low resin exchange loadingRecoflo® uses less than 15% of the total exchange

capacity of the resin compared to conventional ion

exchange processes that use resin to near

exhaustion.

high purity ~ simple package ~ proven reliability

Recoflo® Water Softener

Fine mesh resinRecoflo® uses Eco-Tec specified resin with a resin

bead particle diameter of one-quarter the size of

resin used by conventional ion exchange systems.

Compressed resin bedsRecoflo® resin beds are at a state of compression at

all times, with no freeboard.

Counter-current regenerationRecoflo® uses counter-current regeneration to ensure

that the cleanest and most effective, resin is at the

bottom of the bed after regeneration.

Why Use a Recoflo® Demineralizer?

Advanced Filtration and Ion Exchange Softener Systems

Produced WaterTreatment Systems

Produced Water Treatment

Problem

Extraction of heavy oil often involves the production of steam for injection into the formation (steam �looding,

cyclic steam, SAGD). In order to minimize or eliminate the consumption of fresh water to feed steam generators,

produced water (the water which comes to the surface along with the oil) is often treated and conditioned to a

quality suitable for feed to a steam generator.

Once-through-steam-generators (OTSG) can generally be fed produced water which has been �iltered and softened.

In some cases, initial treatment for silica is also employed.

Produced water �iltration and softening systems which have been used over the past several years often encounter one or

all of the following problems:

• Poor Filtration Quality:

Media �iltration using nutshells or sand media generally do not suf�iciently or consistently remove oil or

suspended solids to adequate levels required for effective ion exchange softening. This results in fouling of

the ion exchange softener resins, which in turn results in:

• Reduction in soft water quality which can affect OTSG performance and maintenance requirments.

• Increased chemical consumption (salt, acid, caustic) for softener regeneration to try to compensate for

partially fouled resin.

• Lower softener capacity due to shorter service runs, longer regeneration and cleaning procedures.

• Increased maintenance costs and downtime in order to clean or replace fouled resin.

• High chemical (salt, acid, caustic) consumption due to the limitations of convention ion exchange softener designs

especially when treating produced water with high hardness or with high total dissolved solids (TDS).

• Safety concerns and costs related to handling hydrochloric acid and caustic which are often used for regeneration of weak acid cation (WAC) softeners.

• Large waste volumes produced during regeneration require disposal.

• Large equipment which requires considerable space and site assembly.

Eco-Tec’s Spectrum Micro-Media FiltrationGreatly improves the quality of �iltered produced water to eliminate many of the problems related to softener

fouling.

Eco-Tec’s RecoPur Ion Exchanger SoftenersProvide signi�icant bene�its in softener performance such as:

• 40-80% reduction in salt and waste for regeneration compared with conventional softeners treating an

equivalent quality and quantity of water.

• Eliminate the use of acid and caustic for regeneration of WAC softeners.

• Compact, skid-mounted, factory assembled systems.

• Fully automated, easy to operate and maintain with easy adjustment to variable feed water conditions and

effective in-situ resin cleaning.

Superior �iltration performance to eliminate many of the problemsrelated to ion exchange softener fouling

The layer of micro media has a very small particle size and acts as a barrier to small

suspended solid particles. The Spectrum micro media is proprietary, inert, long-life (virtually

permanent) media. It is much heavier in density than nutshells or sand which ensures that it

reclassi�ies (resettles below the nutshells after backwashing) and is virtually impossible to

backwash out of the �ilter vessel.

* Spectrum Plus �ilter is used with oily water and has nutshell course media. When very little oil ispresent, a Spectrum Filter with anthracite as coarse media is used.

Designed for simple, low cost operation• Media is effectively scoured using air or gas - no separate pumps or agitators are

required

RecoPur Ion Exchange Softeners

Recopur softeners use Eco-Tec’s proprietary Reco�lo ion exchange process which improves theperformance of ion exchange.

Reco�lo has been used for over 40 years in a variety of industrial water treatment and chemicalprocess applications with more than 1,500 systems installed worldwide.

Key features include:

The combination of Reco�lo features allow:

• Fine Mesh Resin

Finer mesh resin pack more surface area into

the same volume

• Compressed Short Resin Beds

Compressed resin beds promote uniform

�low distribution and plug �low conditions.

• Counter-current Regeneration:

With counter-�low regeneration, the brine passes in the opposite direction to the service �low

water.

• High capacity, compact equipment.

• Production of high purity water.

• Low chemical consumption.

• Low waste production.

RecoPur Softener


A Variety of Softener Con�igurations:

SAC (Strong Acid Cation)

SAC/WAC (Strong Acid Cation/Weak Acid Cation)

Features:• Very simple system with compact foot print.

• Salt consumption is typically 30-60% less than conventional softeners.

• No need for two stage (SAC/SAC) to achieve performance.

Features:• Achieves very low hardness.

• Use only brine for WAC regeneration

• Less brine consumption than SAC only con�iguration.

• No hydrochloric acid or caustic used.

Typical Application:

Feed TDS < 14,000 ppm

Feed hardness < 1200 ppm

Softened Water Quality < 0.2 ppm


Feed Hardness < 1,200 ppm



SAC/WAC/BDH (Strong Acid Cation/Weak Acid Cation/Brine Dehardener)



Features:• Achieves very low hardness.

• Uses less brine than SAC / WAC con�iguration so greater economy for larger capacity systems.

• Can be con�igured to any salt – even salt containing hardness

• No hydrochloric acid or caustic used



Feed Hardness < 1,200 ppm


How Is WAC RegenerationAchieved Using Only Brine?

• Since WAC is only a polisher, it has lowhardness loading.

• A large excess of brine is used for theWAC but the waste brine from the WAC isused directly to regenerate the SAC efficiently.

• Brine must contain low hardness by eitherusing low hardness salt or by softening brinewith the Brine Dehardener (BDH).

SAC/WAC Skid-mounted Softener


WAC/BDH(Weak Acid Cation/Brine Dehardener)


Feed Hardness < 800 ppm

Softened Water Quality < 3 ppm

Features:• Allows softening of very high TDS water.

• No hydrochloric acid or caustic required.



What is a Brine Dehardener(BDH)?

A Brine Dehardener (BDH) is a RecoPurion exchanger (fine mesh resin, compact,packed resin bed) using a proprietary resinthat can separate hardness salts (CaCl2,MgCl2) from brine (NaCl) using only waterfor regeneration. This allows waste brinesto be treated and reused to minimize saltconsumption and brine waste. The wastesolution contains the dissolved hardnesssalts and can be injected into a waste well

since it contains no solids.

Eco-Tec has supplied hundreds of “waterregenerated” resin systems for acid-salt

(APU) and salt-salt (SSU) separation.
